目的:研究电子束辐照对泥蚶微生物数量及其感官质鼍的影响.方法:泥蚶经不同剂量电子束处理,测定辐照后及冷藏期间菌落总数、大肠菌群及其感官评分.结果:电子束辐照能有效地杀灭泥蚶中的微生物,经过0、1、3、5、7、9kGy不同剂量处理,泥蚶的菌落总数逐步下降,当泥蚶的初始菌落总数为3.10×10~5CFU/g时,D_(10)=3.12kGy;泥蚶的感官质量与辐照剂量有关,经过7、9kGy剂量处理后样品产生令人不愉快的异味.结论:结合辐照后及冷藏期泥蚶的微生物和感官指标,泥蚶电子束冷杀菌的适宜剂量为3～5kGy,经3～5kGy处理后,泥蚶的货架期由对照组的5d延长至15～19d.

Tegillarca granosa was treated with electron beam irradiation, and its effect on total plate count, coliform count and sensory quality of Tegillarca granosa were studied. Results showed that electron beam irradiation could effectively reduce the total plate count and coliform bacteria in Tegillarca granosa, and the total plate count decreased gradually with the radiation dose at 0, 1, 3, 5, 7, 9 kGy. The D_(10)value was 3.12 kGy when the total plate count of Tegillarca granosa was 3.10×10~5 CFU/g before irradiation. The sensory quality of Tegillarca granosa was effected by the radiation dosage, and off flavor appeared in Tegillarca granosa treated with 7 or 9 kGy radiation. Thus 3～5 kGy was the optimal dosage, and shelf life of Tegillarca granosa treated with 3～5 kGy radiation could be extended from 5 d to 15～19 d.
